To diagnose oral cancer, your doctor will examine you, feeling for lumps or tissue changes on your head, face, neck and inside your mouth. Your doctor will look for any sores or discolored tissue, and ask about any symptoms.
Your doctor may order tests, such as:
- Oral brush biopsy, a painless test that gathers cells from a suspicious bit of tissue
- Scalpel (knife) biopsy
- Imaging tests such as X-rays, CT or MRI scans to determine if the cancer has spread
